SO I have a macbook pro, (the one before the one released during summer) and just recently bought an HDMI cable and the adapter for it. for some reason I can't get the resolutions to fill the screen completely or filling it too much! overscan is on and it fills it too much, if its off, it leaves a black space between my "screen on the tv" and the actual size of the tv. I have tried it on (i think its a 32 inch sharp tv) and also on my 22 inch emerson that i actually bought to use with my computer.. its making me mad! please help! ive gone to preference and messed with it so much i ran out of ideas
